Congratulations to this image, Terje!!!
It might be not very constructive, but there's not too many stuff, that's really improvable. I've seen photographs, that are a lot noisier than your image, and I have no idea, what's wrong about the shoreline.
I love it, and I know, if anybody finds something that should be improved, you'll find a way to make your scene even better, although it's hard for me to imagine....
